I noticed this comment in the '99 Revenge of the Son of Lisp Machine
paper:
"An early version of MrEd supported bundles of parameter values as
first-class objects, called parameterizations. ... This generalization
turns out to be nearly useless in practice ... Worse,
parameterizations defeat the essential purpose of parameters for
separating global state from thread-specific state."
Of course, parameterizations are back. What was the change in thinking
that led to bringing them back?
Thanks,
Dave
